Running Effect

 

Some code:

Dateformat df = new simpledateformat ("YYYY mm"); numberformat NF = numberformat. getnumberinstance (); standardxytooltipgenerator toolg = new standardxytooltipgenerator (standardxytooltipgenerator. default_tool_tip_format, DF, NF); Renderer. settooltipgenerator (toolg );

 

Add the code to display the corresponding graph points.

Xylineandshaperenderer = (xylineandshaperenderer) _ xyplot. getrenderer (); // sets the grid background color _ xyplot. setbackgroundpaint (color. white); // set the grid vertical line color _ xyplot. setdomaingridlinepaint (color. pink); // set the grid horizontal line color _ xyplot. setrangegridlinepaint (color. pink); // set the distance between the graph and the XY axis _ xyplot. setaxisoffset (New rectangleinsets (0d, 0d, 0d, 10d); // sets whether the curve shows the data point xylineandshaperenderer. setbaseshapesvisible (true); // set the value of each data point in the curve.
